A method and system for realizing dynamic adjustment of electronic cam

Abstract

The invention belongs to the field of cam automation control, and specifically discloses a method and a system for realizing the dynamic adjustment of an electronic cam. The method includes: preparing spindle CAD continuous trajectory files for multiple tasks, the main control program sequentially generates buffer table data for multiple tasks, and then performs data transplantation on the buffer table data according to a set signal to generate an axis control task The current table data, and the current table data read by it are interpolated to obtain the set signal of the main shaft, and then the set signal of the main shaft is converted to the axis pulse to obtain the pulse signal of the slave axis to control the motor Execute slave axis actions. The system includes CAD continuous track files, a table reading and writing module, a main control module, a servo driver and a motor. The invention realizes the dynamic adjustment of the cam by dynamically changing the data table or parameters, improves the flexibility of the function of the electronic cam, and expands its application range.

Description

technical field [0001] The invention belongs to the field of cam automation control, and more specifically relates to a method and system for realizing the dynamic adjustment of an electronic cam. Background technique [0002] The electronic cam is a software system that uses the constructed cam curve to simulate the mechanical cam to achieve the same relative motion between the camshaft and the main shaft of the mechanical cam system. Compared with mechanical cams, electronic cams are more flexible, which is reflected in the realization of curve modeling practical software, low cost, reusable and high precision. Therefore, electronic cams can replace mechanical cams and are widely used in mechanical processing, water conservancy and hydropower, printing, Sewing industry. [0003] Under the process of industrial automation, the performance of control systems and servos has been widely improved. Various light and heavy industries have also put forward higher speed, higher pr...

[0003] Under the process of industrial automation, the performance of control systems and servos has been widely improved. Various light and heavy industries have also put forward higher speed, higher precision, and higher stability requirements for industrial control. The traditional motion control card based The electronic cam implementation scheme combined with the servo motor is difficult to complete the calculation or obtain the next task in a short time, or to add a load to the main control task, and then it is difficult to realize the dynamic adjustment of the electronic cam, and it is difficult to meet the dynamic control of axes in more fields. need
